Question

Match the List-I with List-II and select the correct answer from the given Codes.

List-I	List-II
(Compound)	(Oxidation state of nitrogen)
$N_2{O}_5$	$-2$
$Na{N}_3$	$+5$
NO	$-1/3$
$N_2{H}_4$	$+2$

• A. A-(ii), B(iii), C-(iv), D-(i)
• B. A-(i), B-(ii), C-(iii), D-(iv)
• C. A-(iv), B-(i), C-(ii), D-(iii)
• D. A-(iii), B-(i), C-(iv), D-(ii)

Answer 1

The correct option is A A-(ii), B(iii), C-(iv), D-(i)

1.$N_2{O}_5$

Oxidation state of oxygen=-2

So oxidation state of nitrogen=+5

2.$Na{N}_3$

Oxidation state of sodium=+1

So oxidation state of nitrogen=-1/3

3.$NO$

Oxidation state of oxygen=-2

So oxidation state of nitrogen=+2

4.$N_2{H}_4$

Oxidation state of hydrogen=+1

So oxidation state of nitrogen=-2
